Low dose temazepam improves sleep at high altitude

Many people sleep poorly at high altitude, but hypnotic and sedative drugs are generally considered to be contraindicated because they are thought to impair arterial oxygen saturation. However, in a study done at a base camp on Mount Everest (altitude 5300 m) Dubowitz (p 587) found that low doses of temazepam improved the quality of sleep without affecting oxygen saturation, possibly because they reduced the number of periods of desaturation.
